5 Claims. (Cl. 20-50) My invention relates to a new and useful improvenient in a window construction and has for its object the provision of a window construction whereby windows may be slidably vmounted in their frames and yet so constructed and arranged as to be swingable intoopen position, thus rendering the exterior of the window accessible from the interior of' the room so that a washing of N, the outsiderof the window maybe effected from Io' manufacture, durable, highly efficient in use, and

easily and quickly operated.

Another object of the invention is the provision in a window construction of this classof window stops so` arranged and constructed that they may be moved into position to perform their ordinary functions and moved out of position for permitting the swinging movement of the window to open position.

Another object of the .invention is the provision of a window frame so arranged and constructed 4that the `lower Window may be slid upwardly a sufficient distance so that the upper window, when it is slid downwardly, may have sufcient clearance for swinging inwardly to open position.

Other objects will appear hereinafter.

' The invention consists in the combination and arrangement of parts hereinafter described and claimed.

In the drawings I have shown the invention applied to a window which consists of the window frame embodying the side members I and IBL, the top member I'I' and the sill I8. Slidably mounted in this frame are the upper and lower window sashes, each embodying side rails I9 and 2G, a top rail 2I and a bottom rail 22. A strip of molding 23 serves to cover the top member I'I which is connected by the board 26 and the board 25 to the stepped-down portion 26 ofthe top rail. This stepped-down portion 26 is at the rearward part of the frame. Extending vertically to form a cover for the forward end of the front section of the side member I6 is a molding strip 2l. A similarmolding strip 28 is mounted in front of the side member I5 and projected beyond the back thereof. FiXedly mounted on the inner surface of the side member I6 is a stop strip 29. A similar stop strip 36 is mounted on the inner surface of the side inember I5 and swingable relatively thereto on the hinge 3l. Formed integral with the section I 5 of the side member I6 and projecting inwardly therefrom is the guide strip 3|. The side member I5 is provided with a rearwardly positioned section I5 spaced from the forward part of the side member I5, a guide strip 32 being slideably positioned between the forward part of the side member I5 and the rear section I5. f This guide strip 32 is slidable and preferably formed of metal and adap-ted to engage the wear plates 33 and 34 which are mounted on the side member I5 and its section I5', as clearly shown in Fig. 2. Projecting inwardlyfrom the inner face of the section I5 is a stop strip 35, and a similar stop strip 36 projects inwardly .from the inner face of the side rail sectionV I6, to which is fastened the securing plate 37. The molding 28, together with the securing plate 38 and the closure plate 39 forms a window box at one side of the structure. The sections I6, and I6 and I6" of the side member are connected by the closure strip M. Mounted on the top of the frame are pulleys 43 over which are extended the flexible cords l2 which are connected at one of their ends to a window weight 4I and at their opposite ends to one of the sashes. Connected to the side rail I9 of the upper window sash by means of the hinge 45, is the stem or trunk 46 of a T-shaped structure, having the arms Y5l and 48 (see Fig. 2), this T shaped structure bears against the wear plates 49 and 5I) Vshown in Fig. 2, the angularly turned portions of which lie in a recess 5I formed in the section I5" and I6 of the side member I6 of the window frame. The outer surface of the T shaped structure is a comparatively snug fit with the inner surface of the closure plate 44. (See Fig. 2.) The trunk l5 serves, in addition to guiding the window in its upward and downward movements, as an anchorage for the swinging movement of the window.

Hingedly connected to the side rail I9 of the lower sash is the trunk 52 of a T shaped structure, the arms 53 and 54 of which lie in the recesses 55 and 58 formed in the window frame side member sections I6 and I8 and bear against the wear plates 51 and 58, as shown in Fig. 2. Thus the lower window sash is slidably mounted in the window frame and when the stop 38 is swung to the dotted line position shown in Fig. 2, the lower window sash may be swung outwardly into the dotted line position shown in Fig. 2, when the lower window sash is raised above the sill plate I8'.

It will be noted from Fig. 3 that by stepping down the top plate of the window frame there is provided a space 59 positioned above the uppermost position of the top rail 2l of the upper window sash. When it is desired to swing the upper window sash inwardly into the position shownin Fig. 8, it is necessary that the lower window sash be raised upwardly until its upper rail 2l engages the upper-most part of the space 59. Thereupon, upon a lowering of the upper sash, its upper rail 2| will be positioned below so as to clear the lower rail 22 of the lower sash, and an outward swing- Y ing of the same into the position shown in Fig.

8 may be eifected when the stop 32 is withdrawn from the position shown in Fig. 2 and moved into the position shown in Fig. 8. In order to accomplish this, I mount in the compartment 60 (see Fig. 2 and Fig. 4) a mechanism consisting of a pair of vertically extending rods 6l and 62 which extend through and are xedly attached to a plurality of spaced plates 63, 64 and B5. The plate 64 is connected Xedly to the rod 66 which eX- tends through the bushings 61 mounted in the molding 28 and which is provided with the gripping knob 68. The plate 64 rides in a guide groove formed in the guide plate 69 mounted on the side member sections l5 and l5' of the window frame so as to span the space 10 in which the stop 32 engages. The plates 63 and 65 similarlyA are the spaced rods 13 and T4 which embrace the plates 63 and 65. The rods 13 and 14 in each set are connected with each Yother by means of a pin 15 which engages in a slot 16 formed in the plates 83 and E5. This pin and slot connection is a cam construction so that as the plates 63 and 65 are moved outwardly into the position shown in Fig. 8, the strip 32 will be drawn inwardly to lie flush with the side member sections l5 and I5 of the window frame, thus permitting the sash toswing outwardly into the position shown in Fig. 8. If the window has been swung into its closed or normal slidingposition, an inward thrust on the rod 66 will eifect through the camaction resulting from the pin 15 and the slot 15, an outward movement of the stop strip 32 into the position shown in Fig. 2. VIt will be noted that the slot 15 inclines through the major portion of its length to the direction of movement of the members 63 and B5 and terminates at each end in a portion l1 directed parallel to the direction of movement of the plates 63 and 65. This terminal portion serves as a lock for locking the strip 32 in either its operative or inoperative position, the strip 32 being in its inoperative position when moved into the position shown in Fig. 8. The windows are each provided with weights on opposite sides as clearly shown in the various views and it is not believed to designate these parts with individual reference charactersv is necessary, as they are of a structure well known.

One' of the principal difficulties encountered .with a swingable window is that it is quite imas the window stops used with an ordinary slid-v ing window so that a swingablewindow is provided which is as leak proof as the ordinary slidable window. The advantages of a slidable window are present as well as the advantages of a swingable window, with the disadvantages referred to eliminated. The construction is one which lends itself to an economical manufacture and at the same time provides easy access to opposite sides of either of the window sashes.

While I have illustrated and described the preferred form of construction, I do not wish to limit myself to the precise details of structure shown, but desire to avail myself of such variations and modifications as may appear within the scope of the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letter Patent 1.
